2. Description of Related Art

It is known that currently there are numerous designs and configurationsof heating apparatus for brewing or boiling hot drinks in the industry,among which that are directed to brewing including such as tea bags,coffee powder hot drink machines 80 (as shown in FIG. 1). The hot drinkmachine 80 is configured to comprise a reservoir 10 for containing rawwater and a conduit pipe 20 extended from a bottom of the reservoir 10and connected to an internal heating assembly 30 of a column shapehaving an electric heating liner 40 externally surrounding an outercircumferential thereof An outlet along the column shaped internalheating assembly 30 is also connected to a conduit pipe 20 that isfurther connected to a sprinkler outlet 201 provided on top of theentrance of the brewing container 60. A gate 50 is provided on theconduit pipe 20 adjacent to the sprinkler outlet 201 to control theopening or closing of the hot water. Furthermore, a boiler bottle 70 forcontaining brewed or boiled hot drink is provided underneath the brewingcontainer 60.

Although the abovementioned hot drink machine 80 is able to heat the rawwater entering into the column shaped internal heating assembly 30 to apredetermined temperature during its use, the electric heating liner 40for heating the raw water is being provided to directly surrounding anouter side of the internal heating assembly such that the raw water inthe column shaped internal heating assembly cannot be completed orentirely heated.

SUMMARY OF THE INVENTION

The present invention is an improvement to a heating apparatus of a hotdrink machine that can be used for brewing any types of hot drinks inorder to overcome existing drawbacks of such machine during its usessuch that the raw water entering into the internal heating assembly ofthe hot drink machine to be heated to a predetermined temperature isable to utilize an electric heating liner capable of distributing heatuniformly to a stainless steel pipe containing raw water therein andprovided in said internal heating assembly and such that the heating ofthe internal assembly is of a better heat conductivity to substantiallyincrease the heating efficiency of the internal heating assembly.

A first objective of the present invention is to provide a hot drinkmachine comprising a reservoir for containing a raw water, a conduitpipe extended from a bottom of said reservoir and connected to aninternal heating assembly, a conduit pipe connected between an outlet ofsaid internal heating assembly and a sprinkler outlet provided on a topof an entrance of a brewing container, a gate for controlling opening orclosing of hot water provided on a section of said conduit pipe adjacentto said sprinkler outlet; characterized in that said internal heatingassembly comprises an electric heating liner externally surrounding anouter circumference of a stainless steel pipe of a predetermineddiameter, and an aluminum material die casted to encompass said electricheating liner on said outer circumference of said stainless steel pipe;whereby during a heating process of said raw water entering saidinternal heating assembly, heat from said electric heating liner isuniformly distributed on said stainless steel pipe containing said rawwater via said aluminum material encompassed said outer circumferencethereof such that said heat is uniformly transmitted to said raw waterentering said internal heating assembly to increase a heating efficiencyof said internal heating assembly.

A second objective of the present invention is to provide a hot drinkmachine comprising hot drink machine comprising a reservoir forcontaining a raw water, a conduit pipe extended from a bottom of saidreservoir and connected to an internal heating assembly, a conduit pipeconnected to an outlet of said internal heating assembly to a sprinkleroutlet provided on a top of a brewing container, a gate for controllingopening or closing of hot water is provided on a section of said conduitpipe adjacent to said sprinkler outlet; characterized in that: saidconduit pipe connected between said reservoir and said internal heatingassembly is provided with a receiving space adjacent to said bottom ofsaid reservoir; at least two water-level sensors are provided in saidreceiving space whereby when a water level in said reservoir is lowerthan said sensors, electricity to said internal heating assembly is shutoff by a sensor signal transmitted from a circuit board connected tosaid sensors such that heating of said internal heating assembly isstopped to prevent any idle heating.
